NUT-LOCK- Specification of Letters Patent.

Patented March 26, 1907.

Application filed April 30. 1906. Serial No, 314,493.

To all whom it may concern.-

Be it known that we, MERTON ELLIs and EDWARD AUGUSTUS BOWEN, citizens of the United States, residing at Huntington, in the county of Cabell and State of West Virginia, have invented a new and useful Nut-Lock, of which the following is a specification.

This invention relates to nut-locks applicable to nuts employed for any purpose, but

more particularly applicable for locking the nuts employed upon railway-rail oints, and has for its object to improve the construction and increase the efficiency of devices of this character.

With these and other objects in view, which will appear as the nature of the invention is'better understood, the invention consists in certain novel features of construction, as hereafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation.

' In the drawings, Figure 1. is a side elevation of a railway-j oint with the improvement applied to the clamping nuts and bolts of the same. Fig. 2 is a detail view in section on the line 2 2 of Fig. 1. Fig. 3 is a transverse section, enlarged, on the line 2 2 of Fig. 1. Fig. 4 is a perspective view of the spring-ring detached. Fig. 5 is a perspective view, enlarged, of a portion of the locking-plate detached. Fig. 6 is a perspective view of the improved device applied to a structure other than a railway-rail joint.

The improved device may be applied to nuts used singly, as in Fig. 6, or to a plurality of associated nuts in railway-rail joints, as in Figs. 1, 2, and 3.

In the illustration shown in Figs. 1, 2, and 3 the rails are represented at 16 17, the clampplates at 1.4 15, the clamp-bolts at 13, and the nuts at 12 of the usual construction.

The improved device comprises a plate 10, having recesses 11 for bearing over the nuts 12, the plate being long enough and provided with recesses enough to'bear over all the nuts of the series with which it is associated, and with the ends extended laterally, as at 8 and 9, or at right angles to the plate and bearing against the body of the plate 15 to cause the plateto engage the nuts midway of the same, as shown in Figs. 2 and 3. Located at one or more points upon the plate 10 are projections or arms 18, provided with apertures 19 and adapted to be folded over with the apertures bearing over the portion of the bolt which projects beyond the nut, as shown in Figs. 1 and 2. A resilient washer, preferably of metal, as at 21, is associated with the nut and the turned-over portion of the arm, and a pin 19 is inserted through the bolt 13, as shown in Fig. 3, and operating to prevent accidental displacement of theparts.

By this means a strain is applied to the plate and all rattling or looseness prevented. When employed upon a railway-rail joint, two of the arms 18 will preferably be employed, as shown in Fig. 1.

By this simple means the plate 10 is firmly locked in position upon the bolt, while the spaced recesses 11 effectually prevent the rotation of the nuts, and thus form a very efiectual and simple nut-lock.

The pins 19 will preferably be of the spring-key form, so that they can be readily inserted and removed when required and may be repeatedly used, so that the locking member may be detached when required without injury thereto.

The device is strong and durable, may be readily applied to all forms of nuts and to nuts employed for various purposes, and may be made of any size or strength desired.

When employed upon a single bolt, as shown in Fig. 4, the plate 10 will be arranged to bear at the lower edge upon a portion of the structure through which the bolt 13 passes, as represented at 20, to prevent the rotation of the plate upon the nut.

Having thus described the invention, What is claimed is- 1. A device for locking nuts consisting of a plate having the ends bent at right angles thereto and with a perforated arm extending from one edge and a nut-engaging recess in the other edge, said recessed edge and bent ends adapted to bear against the structure engaged by the bolt and holding the plate from turning and said arm adapted to be bent over the nut and engaging the bolt in advance thereof by its aperture.

2. The combination with a body and a clamp-bolt and its nut, of a locking device for said nut consisting of a plate having an intermediate recess and laterally-projecting ends and with an arm projecting therefrom oppoj 4. The combination with a railway-rail site said recess and provided with a transr joint including the adjacent rail ends clampverse aperture, said recess adapted to bear l plates and their nuts, of alocking device con- 25 over said nut, with the lateral ends bearing sisting of a plate having lateral projections 1 5 against the body and the perforation of the j at the ends for bearing against the clamparm bearing over the bolt in advance of the I plate and with spaced recesses for bearing nut, a resilient washer associated with said over the nuts, said plate having one-or more nut, and fastening means carried by the bolt arms provided with transverse apertures and 0 and bearing against the perforated arm. adapted to be bent over the bolt and bear ro 3. The combination with a railway-rail over the same, a resilient washer associated joint including the adjacent rail ends clampwith said nut, and fastening means carried plates and the clamp-bolts and their nuts, by said bolt and bearinguponsaidperforated said bolts having transverse apertures through arm. their threaded portions, of a locking-plate In testimony that we claim the foregoing I 5 having a plurality of recesses corresponding as our own we have hereto affixed our signato and adapted to 1bear over said 111158 wijih tures in the presence of two witnesses. one or more eXtenc in arms a apte to e folded over one or mof e of the nuts and pro- I i%% BOVEV vided with apertures for bearing over the ad- I k i 2o acent bolts, and locking-keys adapted to en- Witnesses:
